The solution is, of course, to use geometry managed dialogs, and widgets 
that think about their contents before displaying.

I have implemented something like that in my KTypeLayout class, which I 
use to build the Krn dialogs.

It has currently two problems:

1) It doesn't adjust size if you are seeing the dialog. If you exit the 
   app and restart it will work ok.
2) It's basically just one huge memory leak ;-)
   Since I use it to create dialogs that never get destroyed, I don't 
   care, but I can see this would be a problem for general use.

If you want examples, just look in the Krn sources (all dialogs are built 
with this).

If a dialog doesn't display nicely with any font, it's a bug.
